3 Claims.

My invention relates to closure operators, locks and. articles of a like nature, and has for its object ,to provide a new and highly efficient garage or swinging door stop and lock.

A further object is to provide a sturdily constructed control device for garage doors which limits the amount of openingof the door to a predetermined amount, locks the door in the open position, until manually released and which also locks the door closed when desired.

A still further object is to provide a simple economically operated garage door lock which will hold the door open when desired, or which may be utilized to lock the door in the closed position and which device will be positive in its action and will not slip or loosen, due to wind or other causes shaking the .door.

In the drawing Figure 1 is a plan View of a section of the door frame with the door shown in the locked open position.

Figure 2 is an enlarged view of a section of the top of the door and frame with my device shown holding the door locked in the closed position with parts of the door and bar cut away.

Figure 3 is a view of the door frame with my bracket attached thereto showing the bar in the locked position with the door removed.

Figure 4 is a plan view of the rod and bracket in open position, parts cut away and other parts sectioned.

Figure 5 is a plan view of the locking bar.

Figure 6 is a perspective view of the support and locking bracket. r

3 Figure 7 is an end view of the eye part of the eye bolt shown in Fig. 4.

In the drawing I have shown the door as A, the frame as B, and the bracket for my device as C. The locking bar of my device is shown as D and is made of a hollow tube having one end flattened at 5 with a hole 6 transversely through the flattened end 5 through which an eye bolt 1 is passed forming a pivot for the end of the bar D. The threaded end 8 of the eye bolt is passed through the door A and secured thereto by a nut 9. The other end of the tube is cut on an angle at I!) and has a locking pin ll passed through the tube near the angled end 10 said pin and end to drop into a channel in the support 50 and locking bracket C. The bracket C is provided with a horizontal base l5 through which securing screws are inserted to secure the bracket to the frame cross piece l6 of the frame B. Integral with, and depending from this base I5 is a 5 vertical plate I1 formed by bending the plate l5 at right angles and with the lower end of the plate ll at right angles thereto and then back, parallel thereto, to form a channel It? having the two sides thereof parallel and with the top edge of the inside edge [9 of the channel spaced from 5 the base it as shown at 26 in the drawing, Figures 4 and 7.

Through the vertical plate I! which forms one side of the channel l8 of the bracket C, I provide an opening or slot it through which opening the 10 locking and control bar D of my device is carried and operated. A notch 24 is cut in the bottom side of the bar D near the flattened end 5 to provide a locking notch in which the edge l9 may fit when it is desired to use the device to lock the 15 door in the closed position where the device is being used on a door in a garage or building having another separate entrance thereinto.

The operation of my device is as follows:

The bracket 0 is mounted by suitable screws or 20 bolts onto the under side of the cross piece lb of the door frame B and the eye bolt is secured through the door. The bar is passed through the opening or slot 2i in the bracket and is then ready for use. When opening the door, the end 25 of the bar will drop by gravity into the channel It of the bracket with the angled end ID of the bar fitting against the upturned side It locking the door open with the locking and limiting pin ll engaging the side ll of the channel wedging 30 the end of the bar D in the channel 18 and in the slot 2|. When in this position no movement of the door can dislodge the pin it and beveled or angled end 10 from the channel I8.

When it is desired to close the door, the bar is elevated, lifting the end it] and pin H from the channel It, and the door may then be closed, the bar sliding along the top edge of the side l9 and when the bracket is set to lock the door closed, the notch 24 comes into use. 'When the door is so closed, the weight of the bar D will cause it to engage the notch 24 with the edge IQ of the bracket, thereby locking the door closed until such time as the bar is again manually elevated for opening the door. When it is not desired to lock the door from within, the bracket C may be set so far from the door when in the closed position, that the notch 24 will not come into contact with the channel edge l9 and therefore the conventional method of locking the door may be employed.

Having thus described my invention I desire to secure by Letters Patent and claim:

1. In a door lock and catch of the class described the combinationof a bracket having a depending channel along one edge thereof and a vertical slot through the depending edge; a sliding bar carried through said slot having one end pivotally secured to the garage door and the other end cut on a slant and adapted to drop down into said channel when the door is opened; and a pin passed through said sliding bar near the slanting cut end to limit the outward movement of the door, and aid in locking the slanting end in the channel.

2. In a door lock of the class described, the combination of a bracket formed with a base plate for attachment to a door frame in a horizontal plane; a flange extending from said base plate and having its end formed'into "a channel the outer lip of said channel being spaced from said base, said flange having an opening therethrough; a locking bar carried in saidbper'iing with one end secured pivotally to the door and the other end slidably carried in said opening and having the end cut away on a bevel to fit against the inner edge of 'said channel when the door is opened; and a limiting pin driven through said bar near the end adapted to limit the movement of said bar through said opening.

3. In a garage door lock and catch, the combination of a bracket formed with the top to fit along the door frame on a horizontal plane and having a depending channel formed parallel to said top with a slot through the vertical depending portion thereof; a sliding bar carried through said slot, said bar having one end pivotally secured to the garage door and the other end cut on an angle substantially equal to the engaging angle of the bar to the bracket when the door is in the full open position; a notch cut in said bar near the pivoted end said notch and bar to drop down over the vertical end of the channel of said bracket when in the full closed position to lock the door closed; and a cross pin passed
